piston

Can anyone tell what make piston this is? I think it might be a wossner. Its for a 650 01-03 I’ve had since 2004 when I got the bike but can’t remember what the seller said about it apart from there’s nothing wrong with it.

Where do I find a piston for a 91 501? Husaberg/KTM say's no longer available. Thanks

I dropped my shock off at the shop to have the oil changed. I’m told that when he opened the valve to release the nitrogen, a geyser of oil shot out. He said that the oil and nitrogen were completely mixed and that he had never seen that before. The piston was plastic and a bit deformed. The...

I bought some parts from a dealer that went out of business and I have a 92MM Piston and Liner. Both are new and still in the box but I'm not that versed on older Husabergs. 92MM??? has to be for a 400 conversion. Is that correct? Both parts are special order from Berg and not kept at the...

what is the best piston kit to buy and where :moon:

Hello, I went out riding Friday after work. After about 1 hour of hard dirt road riding, the bike made a dull ticking sound and died. I quickly pulled the clutch. Now the piston is stuck. I started to remove the engine from the frame today, and when I emptied the oil there was LOTS of water...

could be enough meat in the crown to get a dish in pic is truncated, pic is attached as well plenty of rings and a 20mm pin, there are some ducatti pistons that might work but they are over 400gms [attachment=0:wd75ghr8]2010_KTM_RC8_R_pistons.jpg[/attachment:wd75ghr8]

I was on a transfer section at the recent National Enduro @ Upton when my bike died on me. Did the quick basic checks.... oil full....coolant full.... battery terminals all good. Long story short I finally couldn't diagnose the problem myself so I took it to the shop. Turns out I have a...

Hi I need a new piston for my '08 FE550. What make is the standard piston that Husaberg use? Are Wossner pistons any good? They seem it from what I've read. They are also much cheaper than the price I've been quoted from a dealer for an OEM piston- over £250!! Seen the Wossner pistons at...

There is a cheap one on ebay now (brand new Wossner) ... see item #160449146554. Not mine, just happened to see it and figured I'd post my findings here.

i was wondering if the new 570cc piston(100mm) is the same with mine, i own a 2004 fs650 and i want to increase the compression a bit(12.4:1)... :D .If not then what is your suggestion for an aftermarket piston?

i've been assessing pistons and dimensions for some time and as i sell stuff i have had a problem i couldn't cure till today! basically, all the old pistons from the 470, 550 and 650s have a deck 12.7-13.3 above the gudgeon pin. the 2004+ 550 shares the 13.3 measurement but the 450 is...

Hey, it's me again, Mr. broke my whole motor and spending a fortune. Did I join a club? The last thing I've got to decide upon is the scored piston and sleeve problem. I have not yet seen the sleeve or piston, but my mech said both are damaged and in need of replacement. He said that when...

I am replacing the rings on my 600. After I took the top end off the lower oil ring got bent from cleaning. I can't believe how fragile the oil rings are. As I only have only done two stroke's before what is the procedure for installing the rings? Is it best to use a ring compressor...

Hi, In an effort to fit 100mm piston in the place of 92 mm,I had the reconditioner made a bush for bigger 20mm pin but when I got back to him to got the new stuff I realized he had made it out of brass instead of bronze.I am not happy with that.what do you think about brass piston pin bush?

Hi all dose any one know the difference between the 04-08 fc/fe 550 piston compeard to the 03-08 fc/fe 650 & 550 ? cheers Matt

Why does Husaberg recommend a 310mm rotor for use with there 6 piston caliper? Every other company uses 320mm rotors and Husaberg also offers a 320mm rotor for use with the stock caliper. Also, will a 17" x5" rear wheel fit in the FE550e swingarm with a 160/60-17 rear tire or do I have to use...

just wondering dr_c ,whats going on with that piston. thought you were using wossner std pistons because of the flat top & reasonable light weight at 282g. why are you machining weight off the std husaberg flat top piston? do you think it maybe stronger than the std wossner after machining...

Should I be worried? :cry: If I feel with my finger I can't feel the scratches so their not deep. Any idea as to what caused this. Bike is a 2002 650 SM with 1500 km since rebuild, new nicasil on the sleeve, nearly new piston.

Hello Most fairy tales start with once on a time.... For this forum probably more like I had lying on a shelf.... a Wössner piston part #8602DA with casting mark at the bottom W4108. I compared the pistons, too quickly yes, and installed the Wössner piston. The piston comes 0,3 mm above...
